I'm guessing that in the interview it wasn't in English, and it just doesn't translate well.

It was in hindi, my native language. I am sorry couldnt translate that good.

Don't worry about it - I figured it was. Translating jokes and puzzles is never easy, because words often have multiple or subtle meanings, which don't translate well.

Hello Sir,
Please dont be upset with me.
Firstly, It was asked to me. I dint make it up.
Secondly, you cant fold the rope.
Lastly, consider the smilies as balls. You are supposed to move the balls or place the balls.
Combination of (2+1) means either in the first move you pick 2 balls up and then 1 ball or vice versa, your wish.
Thanks,
Rahul

I blame the interviewer for this, not you.
Ok what are you allowed to do with the rope then? If you can only set it on fire and observe it from there on it'll just burn for an hour with nothing you can do about it.

|

Um.
How many ends does a rope have?

You are nearing the answer OG. I guess you might have figured it out
|
|
|
|
|
That's in violation of my stated assumptions. In order to utilize both sides, you have to be able to light it twice, which means you can do more than just light it and then observe.
|
|
|
|
|
Nah - you just touch the two ends together and light them both at the same time! 
(Or light one end from the other, but that produces a slightly less accurate 1/2 hour)

You might have found a loophole.

It's good stuff, this rope theory! Cutting edge...

In this case no noose is good news

Light it in the middle.
You'll never get very far if all you do is follow instructions.
|
|
|
|
|
How do you know where that is?
I would have liked to fold it in half, get the middle that way, then fold it again at 3/4 for part 2 of the question, but OP said no folding..
|
|
|
|
|
I'd fold it anyway. The interviewer sounds an ass. The question is likely something that has morphed beyond recognition with retelling.

Easy: Burn the interviewer first, then fold the rope. 
|
|
|
|

Thanks sir,
well i told him
to measure it for half an hour, burn it from both the sides. He told me, but then nothing of that rope will be left.
I said, as it is even if you cut the rope into half nothing will be left.
He then smiled. Actually i dint understand what was the intention.

|

Where's the constraint about not being able to fold the rope?
|
|
|
|

I think that's the whole point - they expect you to talk about what do and how that would give the desired result - in other words its a test of your ability to reason and explain your reasoning (like so many of these wanky things).
So you could answer. fold rope in half, cut it and get two half-hour burns (ie light them simultaneously), or - as someone else said - light both ends. For the 45 mins, fold in half, fold one half in half again, then light the bend - the longer piece will burn for 45 mins, and so on.
For the smilies, it's easy to see how to move a group of 3 to swap the figure, does that count as 2+1 or 3 - you would be expected to reason that out.
I prefer to talk to someone generally about their work, get them to meet the team and talk about things they've actually done, including some technical discussion and reasons for why they took the approach they did. Simple reasoning tests like this where there is ambiguity, and where you are expected to reason about the answers have more value than many things done at interview, even though I wouldn't use them myself.

Yes Sir,
Thats true. Capability and knowledge is every thing. This aptitude test and all bull sh*t. And on top of that what is the need to impose a criteria like 60% and above throughout academics? Its becoming frustrating now. In one company i cleared all aptitude and technical rounds, however one person who topped throughout his academics flunked these tests. Now what can be said about this? Well i hope these practices are not followed else where.
Thanks and Regards,
Rahul.

Rahul,
I hope these types of tests are used everywhere. And the criteria for being in the top 60% is merely an exclusion of the BOTTOM 40%, which shows someone who did not LOVE the degree, in my book.
And the Guy who did GREAT in school, and FAILED these tests is WHY they (we) give such tests. It is the opposite of working the system. All school tests are solvable. Not all problems in real life are. We need people who can figure that portion out... They have to know what they don't know, or realize they cannot solve the problem BEFORE they just start banging out code.
I use tests like these. Even worse... How many molecules of rubber comes off a tire in a single rotation, under normal wear conditions? If the person studied a lot of physics: If I push a fudge brownie out into space from the MIR space station. Will it explode/implode? Please explain?
To be clear, what I am looking for has NOTHING to do with the answer. It has to do with the reasoning, and their reactions to the question, and their follow-up questions.
Honestly, put yourself in their shoes. If you had 1,000 people to interview for 100 positions, and you wanted to hire the types of people who are going to do the best... How would you decide that?
- Personality? (doesn't work)
- Dress? (hardly?)
- Experience (maybe, but if you have 10:1, you probably pay on the low side, and you should, for the new people. Give me someone who wants a chance to prove themselves and have shown this during school)
It is a simple optimization, and a requirement to optimize. Interviewing takes time and costs money.

Hello Sir,
I completely understand what you want to say. I also understand that you are one of the recruiters. I have nothing against these tests. Its just my frustration. I understand the importance of these questions. and speaking about
Quote: And the criteria for being in the top 60% is merely an exclusion of the BOTTOM 40%
and it may also happen that due to bad fate or some family problem or something else, that student might have not performed in his academics, this doesnt mean that he dint respect his degree. You cant take away good and bad fate away from people.
These few people in top 60% are not able to debug something like below scenarios
1)string s="1,2,3,4,5";
s.split(',')[0];
2) Object reference not set to an instance of an object.
What they do is operate on thousands of variables. Throughout their academics the simply mug up the entire book. They have 100% attendance. So they get good internal marks. This is what brings them to 60% throughout.
I completely understand that there are 1000's of candidates and very few to interview and seal the position. Its just that : i just hope that you dont relate marks with intelligence,knowledge and capability. It might happen that in the bottom 40% that you left out might be a promising candidate.
One of my friends flunked an year due to bad fate. Now he is one of the best Dot Net architects i have ever met.
Today's generation dont want knowledge, they just want money, no one is willing to learn. They just want a good package. It is all because of this stupid education system today people lack knowledge.
And yes i understand everything and agree to what ever you said. But i just want to say never let go of a promising candidate. Ok now tell me a person has scored 60% throughout passes the interview, but fails to perform now what will you do? His marksheet, degree, etc all is a waste.
With due respect Sir, i just want to say , my aim here is not to oppose you or to fight with you. But please read the comments of Original Griff(MVP since many years and many people. You will come to know what we are saying please read other comments also. I hope you will realize the importance of an MVP title.) Not judging a person based on his knowledge and capability and taking into consideration his marks is not correct.
I understand optimizing is important, but sometimes there is a wrong optimization. Lastly i just want to say, i apologize if whatever i say has hurt you or i apologize if i was rude. Its just a difference of opinion nothing else. I request you to consider this discussion in a sporty way.
Thanks and Regards,
Rahul

Rahul,
Nothing you said should offend me. When I go to the market for fresh fruit, I DO NOT look at EVERY piece of fruit. I do not look at the bad ones. Once I find what I need, I stop. Will I leave BETTER fruit behind? CERTAINLY.
I was giving you the OTHER SIDE of the story, because WHEN (not if, as I wish) I make a bad hiring decision, the cost is QUITE HIGH. It typically takes 60 days to realize it. That is 2 months of WASTED salary + 2 months of WASTED training + 2 months of LOST opportunity. Oh, BTW, my rule of thumb is a new hire costs 6 months, because it takes those 2 months and other peoples time to get them up to speed. So now it will cost me 1yr of someones salary EVERY TIME I am wrong. For that price, I MUST try not to be wrong. I must play the odds...
Now, there are 3 things YOU should do:
1) Change the conversation. If your OVERALL grades < 60%, maybe you have 90% in your major? Push that!
2) Show up with REAL LIFE examples of work. I got my first programming job at 18. My boss took a risk, but I took a low salary and EXCEEDED his expectations. But I also had excellent references, and I brought with me work in 3 different languages on the machines (PDP-11s) he was using.
3) Do Something. Publish Something. Make something useful. Make Flippy Bird II, the flight of the finger... (pun is intended)... Find out what they are doing, and do something related.
At the same time that I use filters, I will interview ANYONE willing to be put through it, if they show enough initiative... Yes, book smarts alone is not good enough.
Just don't hate the process!
When I start hiring, I get ready for the following:
- Idiots who have typos on their resume
- People who call when an ad says Do not call (I use a pseudonym so the calls get blocked)
- About as many Head Hunters as actual prospects will reach out to me (for MONTHS filling the position)
- People who will claim to be self-starters that "need" a team to work on
- People who outright lie about their skills
- People who have certifications that don't know anything useful
But it is not personal. I sort the resumes into piles:
- Experience and Education
- Just Experience (no formal education)
- Just Education (recent graduates, etc)
- No Experience or Education
- No Clue, errors, wrong job, etc
I start calling from the first Pile. The second and third are only used if I see something I like...
Anyways, I wish you luck. And BTW, one of my favorite ANSI C questions was the result of:
{
int x;
int z[5];
3[z] = 19;
x = 2[z+1];
}
// Will it compile/work? What will be the value of x?
Honestly, I would ONLY ask that question if the interviewee said that their 5+ yrs of C made them an expert at the C language...

Respected Sir,
If according to you i am that fruit in the market which you wont look upon, thats ok. With due respect i dont and i wont hate the hiring process. I again apologize for my language(if it hurt you). I respect every senior person in the industry and you are a senior so i respect you too. And yes i understood the other side of the story. It was nice speaking to you. I will look forward to learn many things from you.
Thanks and Regards,
Rahul
